Genes affected
CEP135 (HGNC:29086): (centrosomal protein 135) This gene encodes a centrosomal protein, which acts as a scaffolding protein during early centriole biogenesis, and is also required for centriole-centriole cohesion during interphase. Mutations in this gene are associated with autosomal recessive primary microcephaly-8. [provided by RefSeq, Jun 2012]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2021The c.226G>A (p.A76T) alteration is located in exon 3 (coding exon 2) of the CEP135 gene. This alteration results from a G to A substitution at nucleotide position 226, causing the alanine (A) at amino acid position 76 to be replaced by a threonine (T). The p.A76T alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
